Lyric discussion by biermanger 

This song is about Iuppiters' fight against his father Saturnus [Castrated father, Swallowed his children whole]. Roman mythology

The tale was actually ripped off from the Greek Mythology. Jupiter's actual name was Zeus(Ζευς) and Saturnus' name's Cronus(Κρόνος), who had indeed castrated his father Uranus, following his mother Gaea's instructions. The tales were adopted by Romans when they had conquered Greece, 2nd-1st century BC, and became infuenced by the Greek culture and literature.
